Patent JP-H0437816-A (JP)
Title: Beam scanner
Inventor: USUI TAKESHI
IPC: B23K26/082
Filed: 1990-06-04
Abstract: PURPOSE:To attain sudden acceleration/deceleration and rapid movement by impressing an acceleration pulse by a driving circuit in a galvanometer at the time of starting movement, and in the case of stopping the movement, impressing a deceleration pulse and restricting pulse width until a prescribed moving distance can be obtained. CONSTITUTION:When digital data 101 specifying a moving destination are converted into an analog signal by a D/A converter 21 and the analog signal is impressed to the galvanometer 11 as an angle control signal 102 through a driving amplifier 22, a detected angle signal 201 outputted from the galvanometer 11 is negatively fed back so as to be equal to the signal 102. On the other hand, the signal 201 is converted into digital data by an A/D converter 24 and used as a monitor signal. In this case, an acceleration pulse is impressed only for a period up to the arrival of the galvanometer 1 to an intermediate position between the angle of a moving source and the angle of a moving destination, and at the time of deceleration, a deceleration pulse having the same amplitude and pulse width as the acceleration pulse is impressed to control the movement of the galvanometer 11, so that sharp acceleration/deceleration can be attained and rapid movement can be attained.

Title: Rotary head type magnetic video recording and reproducing device
Inventor: KUBO KANJI
IPC: G11B15/087
Filed: 1982-08-23
Abstract: PURPOSE:To corner noise without obtaining a reproduced RF signal, by using an on-track position pulse from a tracking error signal obtained from the processing of a reproduced pilot signal. CONSTITUTION:Every difference signal between a pilot signal on a main scanning track and each pilot signal recorded on both adjacent tracks is extracted by separating the signals, and the amount of shift of a head and the direction from a main scanning track are detected by comparing the reproducing level of both signals to obtain an on-track position pulse PO, which is inputted to a terminal 32. Further, a head switching signal H.SW(a) is inputted to a terminal 31. A monostable multivibrator circuit 36 is triggered by the pulse PO and a signal (e) is outputted. When outputs (b), (e) are dissident, that is, at the H.SW periods A1, A2, A3, an output (c) of a noise cornering pulse generating circuit 37 is obtained. Then, some fraction of the track width of the magnetic tape is transferred, but no output (c) is obtained when the signals (e) and (b) are coincident by transferring.

Abstract: PURPOSE:To improve the resistance to soft-error caused by alpha-ray, by forming a trench reaching an amorphous layer, on the peripheral part of an element forming region, after an anti-oxidizing mask material is formed on the substrate main surface having an amorphous layer in a specified depth, and oxidizing the substrate surface facing the amorphous layer and the trench. CONSTITUTION:By implanting high energy boron ion 5 into a silicon substrate 1, an amorphous layer 4 having high impurity concentration is formed in the silicon substrate 1. A silicon oxide film 10 and a silicon nitride film 7 are formed on the silicon substrate 1 surface, and a trench 6 reaching the amorphous layer 4 is formed. Thereafter, when thermal oxidation is performed, the amorphous layer 4 is preferentially oxidized, and then the surface region of the substrate 1 facing the trench 6 is oxidized. When the silicon nitride film 7 and the silicon oxide film 10 are eliminated, a silicon oxide film 2 is formed, in which the parts between the silicon substrate 1 and the element regions 3 and the parts between neighboring element regions 3 are completely isolated insulatively. Thereby, the possibility in the occurrence of soft-error caused by alpha-ray can be decreased.

IPC: H01Q1/27
Filed: 1994-06-28
Abstract: PURPOSE:To quickly restart reception even in the case of the occurrence of short-time shielding by performing the tracking control at the time when the cosine component of the phase difference of an antenna exceeds a specific threshold. CONSTITUTION:The allowable minimum value larger than the peak value of the side lobe of the cosine component of the phase difference is denoted as a threshold P1, and tracking control is performed when the cosine component exceeds the threshold p1, and thereby, tracking control is difficult to miss even if the reception signal level is reduced by the weather difference. After tracking control is started, a reception signal level A is obtained by square averages of the cosine component and the sine component. The allowable minimum value which is larger than the peak value of the side lobe of the level A in the range of -180 deg.<=DELTAtheta(phase difference)<=180 deg. is denoted as a threshold P2, and the control is released when the level A is lower than the P2; and therefore, deviation from the tracking control range is difficult even if the reception signal level is reduced by the weather difference or the like and a moving body is quickly rotated. Tracking is continued when a BS antenna 1 of the moving body is shileded in a short time by buildings or telegraph poles.
